11.1.3 - 2026-07-10

Improvements

• RadzenSpreadsheet culture-aware editing, display and formulas — the spreadsheet now honors the component's inherited Culture (exposed as a new Workbook.Culture property, defaulting to the current culture). It drives cell input parsing (including comma-decimal entry like 10,50 and day-month date handling), edit and display rendering, number formats (separators, month names and AM/PM designators follow the culture while format codes stay canonical), formula entry and display with Excel FormulaLocal semantics (; argument separators and , decimals in comma-decimal cultures), and dialog input for data validation, conditional formats and filters. XLSX and CSV files continue to read and write canonical invariant values regardless of the workbook culture, and malformed formulas now surface as formula errors instead of throwing. Includes new localization demos for Spreadsheet and Document Processing. Note: headless code on non-en-US hosts now parses string values with the host culture — set Workbook.Culture explicitly (e.g. to InvariantCulture) for host-independent processing.
• RadzenSpreadsheet protected sheets — pasting into unlocked cells of a protected sheet is now allowed. Paste is blocked only when the selection contains a locked cell, and cut & paste can no longer bypass sheet protection. Thanks to @panoskentros! Fixes #2609.
• RadzenChart data labels — each series data label group now carries a data-seriesindex attribute, making it possible to establish a direct link between a series and its labels. Thanks to @wimsoetens-cmd!

Fixes

• RadzenChart: the tooltip is no longer clipped at the chart edge and tooltip placement is now RTL-aware.
• RadzenSlider: the slider now initializes correctly when it starts disabled and is enabled at runtime.
